  • Device for web removal from a cylinder
    Patent number: 4528067
    Abstract: The invention relates to a device for a web, which can be removed from a cylinder (3), said web preferably being a paper web. A band-shaped doctor blade (5), which is designed to extend along the mantle surface (3A) of the cylinder, and which is made possible to be fed in the longitudinal direction of the blade, brings about the removal of the web.The device makes possible a rational and simple forward feed and change of the doctor blade (5), when said blade is worn during its bearing against the mantle surface (3A) of the cylinder, and the time of cost consuming interruptions in connection with the outfeed of the web is thereby reduced, and also the size of the plant is reduced.
